AIR GUN.

Application filed September 22, 1924. Serial No. 739,170.

To all whom it may concern:

Be it known that 1, CHARLES F. Lnrnvnn, a citizen of the United States of America, residing at Plymouth, in the county of lVayne and State of Michigan, have invented certain, new a nduseful improvements in Air Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to guns and particularly relates to air guns.

It is an object of the invention to provide an improved mounting for the closure controlling the opening in the barrel of an air gun through which shot may be introduced into a magazine within said barrel.

A further object is to derive a novel reinforcing function from a guide member for 7 shot mounted upon a tube into which it guides the shot and through which the shot are discharged.

These and various other objects the invention attains by the construction hereinafter described and illustrated in the accompanying drawing, wherein:

Figure l'is a plan view, partially in sec tion, of an air gun barrel embodying the invention.

liigure 2 is a view of the same in axial sectional elevation.

Figure 3 is a cross sectional view taken upon the line 3--3 of Figure 2.

In these views, the reference character A designates the false barrel of an air gun, and B the usual true barrel or shot tube extending centrally through said said barrel. Between said tube and barrel, there is formed a magazine chamber C for shot, an opening I) being formed in the barrel adjacent its outer end for insertion of the shot. E is a closure for said opening formed by-a free end of spring sheet-metal arm E disposed within the barrel A, the other end of said arm being welded or otherwise suitably secured to a cap F which substantially closes the outer end of the barrel A. Said cap has a marginal cylindrical flange which fits into the barrel A, and preferably the arm E is carried by said flange. The cap F has a centralopening and is formed with a cylindrical flange G, marginally of said opening, and projecting into the barrel A, the outer end of the tube B being inserted in said flange G and secured thereto by brazingor the like.

H is a collar mounted fast upon the in nor end of the tube l3 and externally threaded for engagement centrally with a disk H fixed within the barrel A, the inner end of said tube being thus supported in its proper central relation to said barrel. Adjacent to said collar the tube B is Formed with a shot inlet 1 and a sheet metal guide member J is mounted fast upon said tube for directing the shot into said opening from the magazine C. Said guide is of an approximate U-shape, the tube B being extended through its lower portion and being brazed or otherwise suitably rigidly secured to said portion. Portions of said guide projecting above the tube coact with the latter to form a run-way through which shot may travel toward the opening I. v

The presence of the opening I in the tube B tends considerably to weaken said tube, and if the end of the tube adjacent said opening were directly inserted in the collar H, there would exist a possibility of the tube being bent at said opening it roughly or improperly handled. As a sate-guard against such damage, the guide J is integrally formed, at its inner end with a split bushing K which fits into and is secured within the collar H, the inner end of the tube being inserted in said bushing and secured therein. Thus the shot guide reinforces the tube at its weakest point in addition to directing the shot to the inlet located at said point.

lit is an advantage of the structural leatures above described that they facilitate the uniting of the described parts by brazing instead of soldering and this in turn has the advantage that the structure may be' subjected to a higher temperature in bluing than would be possible with a soldered connection.

VVhat I claim as my invention is:

1. In a device of the character described, a gun barrel having an opening adjacent one end thereof for the insertion of shot, a cap forming a closure for said end of the barrel, a closure for said opening, and a spring arm carrying said closure at one end and mounted at its other end upon said cap.

2. In a device of the character described, a gun barrel formed with an opening adjacent one end thereof, a cap forming a closure for said end of the barrel, and a closure for said opening mounted upon said cap and yieldable into the barrel. to permit the insertion V of shot through said opening.

3. In a device of the character described, a gun barrel formed With an-Opemng-ad acent one end thereof, a cap, substantially closing said end and having a flange fitted Within the barrel, a closure for said opening,:

mounted upon said shot tube at one-side of said openingformedWith a bushing embracing said tube at the other side of said opening;

5; Inadevice ofthe character described, a gun'barrel, a shot tube extending through said-barrel andhaving an opening for the admission of shot thereto, a member fixed Within said barrel forming a support for said tube at one side of said opening, and a shot guide mounted upon said tube at'the other side of said opening. and having a portion embracing the tube Within said fixed member.

6. In a device of the character described, a gunbarrel, ashotitube extending through said barrel and having an opening for the 30 admission of shotto said-tube, ashot guide mountedupon said tube at one side of said opening, a support for the tubefixed Within the barrel at the other side of said opening, and a collar rigidly carried by the tube for engagement With said support, said shot guide having an integral portion engaged within said collar.

In testimony WhereofIafiix my signature.
